So my problem is when I first received the phone the vibration feedback when pressing the back/home buttons and keyboard feedback were really great a solid little buzz that gave the phone a quality feel about it much like the HTC. Since the last update XNPH25R (which may just be coincidence) the vibration has become stronger and an audible buzz is now heard from the phone. My question is has anyone else had this problem and would be a hardware and or software problem. Personally I'm thinking its a hardware problem as I tried flashing the original rom prior to the last update and still had the same problem.
Any suggestions or feedback would be greatly welcomed.
